. BASKETBALL In 2005, the average ticket prices for Dallas Mavericks games and Boston Celtics games are shown in the table below. The change in price is from the 2004 season to the 2005 season. Team Average Ticket Price Change in Price Dallas $53.60 $0.53 Boston $55.93 –$1.08
a. Assume that tickets continue to change at the same rate each year after 2005. Let x be the number of years after 2005, and y be the price of an average ticket. Write a system of equations to represent the information in the table. b. In how many years will the average ticket price for Dallas approximately equal that of Boston?
Answer:
a. Let's call the average ticket price for Dallas in 2005 as "d" and the average ticket price for Boston in 2005 as "b". Then the system of equations can be written as:
y_d = d + 0.53x (where y_d represents the price of an average ticket for Dallas after x years)
y_b = b - 1.08x (where y_b represents the price of an average ticket for Boston after x years)
b. To find the number of years in which the average ticket price for Dallas will approximately equal that of Boston, we need to solve the equation y_d = y_b for x. Plugging in the equations for y_d and y_b, we get:
d + 0.53x = b - 1.08x
Rearranging and solving for x, we have:
1.61x = b - d
x = (b - d) / 1.61
Now we just need to plug in the values for d and b from the table:
d = 53.60
b = 55.93
x = (55.93 - 53.60) / 1.61 = 2.33 years
So it will take approximately 2.33 years for the average ticket price for Dallas to approximately equal that of Boston.
Step-by-step explanation:
Answer: a. Let x be the number of years after 2005, and y be the price of an average ticket. Then, we can write the following system of equations to represent the information in the table:
For Dallas:
y = 53.60 + 0.53x
For Boston:
y = 55.93 - 1.08x
This system of equations represents the average ticket price y for Dallas and Boston as a function of the number of years x after 2005, with the change in price from the 2004 season to the 2005 season given in the table.
b. To find the number of years when the average ticket price for Dallas will approximately equal that of Boston, we can set the two equations equal to each other and solve for x:
53.60 + 0.53x = 55.93 - 1.08x
2.33x = 2.33
x = 1
So, the average ticket price for Dallas and Boston will approximately equal each other after 1 year. Therefore, in 2006, the average ticket price for Dallas will approximately equal that of Boston.

b. Graph f(x) with its restricted domain and then graph its inverse on the same set of axes.
c. Find the equation of the inverse of f(x) with its restricted domain.
Answer:
Step-by-step explanation:
a) As the function is a quadratic you could restrict the domain by taking only values either side of the line x = 3. This means the domain will be
a) 3<x<∞
Or
b) -∞<x<3
b) the graph is attached below.
c) The equation of the inverse of f(x) can be found by switching x and y:
X = (y-3)²
√x = y - 3
y = √x + 3
However this takes in positive and negative values of the square root function. So in order to restrict this, we can take the positive square root only.
Thus y = +√x + 3

Find the gradient of the line that passes through (3, 7) and (1, 10).
Answer:
-1.5
Step-by-step explanation:
The gradient of a line can be found using the formula:
gradient = (y2 - y1) / (x2 - x1)
where (x1, y1) and (x2, y2) are the coordinates of two points on the line.
So for the line that passes through (3, 7) and (1, 10), the gradient can be found as:
gradient = (10 - 7) / (1 - 3)
gradient = 3 / -2
gradient = -1.5
So the gradient of the line that passes through (3, 7) and (1, 10) is -1.5.

A circle has a diameter of 26 feet what is the circumference
Use 3.14 for pie and do not round your answer be sure to include the correct unit in it in your answer
The circumference of a circle with a diameter of 26 feet is approximately 81.64 feet.
What is the circumference?
The circumference is the length of any great circle, the intersection of the sphere with any plane passing through its center. A meridian is any great circle passing through a point designated as a pole.
The formula for the circumference of a circle is 2 * π * r, where r is the radius of the circle.
To find the circumference, we first need to find the radius of the circle.
The diameter of the circle is 26 feet, so the radius can be calculated by dividing the diameter by 2:
r = 26 feet / 2 = 13 feet
Now that we know the radius, we can find the circumference:
C = 2 * π * r = 2 * 3.14 * 13 = 81.64 feet
Therefore, the circumference of a circle with a diameter of 26 feet is approximately 81.64 feet.
